Major component of the problem right there. You will need to post the alkalinity before a proper "fix" can be suggested as well as the reading for a new batch of SW
after mixing for Â½ a day. The high Ca
is causing severe stress and most likely polyp bailout.
Several large water changes over the next week or so should help, saltmix readings depending. You have either a Mg
deficiencey causing the Ca
to climb independantly or you have been dosing additives without testing properly. If the alk
is quite low, this will be a Mg
issue. If the alk
is in the right range, you've been using additives. Either way, you need to do some water changes.
I use 50% tap water and 50% ro on the advice of the LFS.
Poor advice, if RO
is available to you, use that alone. Tap water depending on analysis will often promote unwanted algaes and can contribute to No3
and the chemistry adversely. RO
is even better still but definately RO
